This is exactly why I invested in a higher-end drip machine and consistently buy better beans. If my coffee at home sucks, I’ll stop and get some at a shop. And by keeping it in-house I’m definitely coming out ahead in the long-run.

Free coffee machine at work or my instant nescafe at home lol. Stuff shop prices

also if you just want caffeine you can just eat coffee beans or take caffeine pills (with l-theanine optionally or an adaptogen to take the edge off)
